Just 11% of the world flew in 2018.
A tiny group of very frequent flyers, 1% of world population, account for 50% of airline emissions.
A French climate expert called for people to be limited to just four flights in their lifetime. 41% said they were in favour.

A year after it went up online, our paper on the limited effect of #climate considerations in decisions about air travel is finally formally OUT. TL;dr: it will take more than caring about the climate to get people to fly less...

There can be no *new* oil and gas drilling if we want a safe, habitable world.
Yet, a tiny club of wealthy countries – 🇺🇸US, 🇨🇦Canada, 🇦🇺Australia, 🇳🇴Norway and 🇬🇧the UK – are responsible for *51% of all planned oil and gas field developments* from now to 2050.
That's the real hypocrisy ahead of #COP28

This is from Robbie Andrew's great EV data page.
The 'new sales' data always gets picked bc it looks way more dramatic than the actual change in use of fossil vehicles.
Norway is currently on track to miss its 2030 transport sector decarbonisation targets.

Despite enormous progress on renewable energy worldwide, we simply aren't seeing the overall reduction in fossil fuel use that is the thing we really need to arrest the climate crisis.

Something important to note about Oslo is that most vehicles are *not* electric. It's currently about 27% for the county, based off the latest data. Norway is ~15%
(Oslo is ~37% electric when you only count private passenger cars - electrification of vans is going slow)
